Have you tried SAMe?

I’ve been having all types of weird symptoms like chronic neck pain, head pressure, insomnia, heart palpitations, heart contractions, breathing problems, mood swings, panic attacks, anxiety..etc
I’ve seen medicine practitioners, emergency doctors, cardiologists, neurologists, ENt practitioners..etc with no answer
(My insurance does not cover therapy and psychiatry and at this point of my life money is tight)
I’ve been doing some research and I came across an essay written by Josh Kaufman which talked about SAMe and how it cured his Dysthymia and wondered if it might help me.
I’m seeing my doctor again in two days and I’m nervous to bring it up as I’ve been bringing up the weirdest suggestions and I’m feeling he might start to think I’m going crazy... which I am btw.. I’m tired of all the aches..
I’d like your opinion and/or experience on this before I decide whether or not to consider asking my doctor about it and maybe even purchasing it.
